Libido at zero😢

Tinyiko • I`ve been with my boyfriend for 7yrs and we are planning to get married and planning to conceive.
I'm 15 weeks and 1day. Ever since I found out that I'm pregnant I haven't had any desire for sex whatsoever. I thought that maybe it's just part of the 1st trimester but I still feel the same way. Any advise on what I can do?
